In Sanskrit, the word Krsna means dark’, indicating the supreme Consciousness. Pure Consciousness is said to be ‘dark’, not as opposed to ‘light’, but in the sense that it is unseen by or unknown to one as long as one remains rooted in earthly experiences limited to the realms of perceptions, emotions, and thoughts gained through the physical body and the intellect.
Consciousness is the pure Self, the sentient Life Principle which enlivens one’s material equipment to function in their respective realms. Consciousness is the very subject of all experiences and, therefore, cannot be objectively experienced.
The incarnation of Krşna represents the descent of the infinite Brahman to the material world. The ever-smiling, lotus-eyed Krspa, with a garland of flowers around His neck, is described as being blue and wearing yellow clothes.
Blue is the color of the infinite, Whatever is immeasurable can appear to the mortal eyes only as blue. Vast expanses in nature, such as the sky at midday or the ocean at its depths, appear blue to human perception. Yellow represents the earth. Anything buried in the earth gathers a yellowish hue; and in the fire, earth (mud, silica) emits a yellow hue. Hence the blue form of Krşna clothed in yellow appropriately suggests pure, infinite Consciousness coming down to earth to play in His finite form.
This infinite Lord dwells in the core of our personality as the very Self in us, for whatever exists in the macrocosm also takes place within the human heart, or the microcosm.
The infinite, all-pervading Truth, donning the finite form of a human being, gives the impression that the Truth is fettered and limited. This idea of the illimitable Truth seeming to be limited is well brought out by the fact that Krsna is said to have been born in prison.
